IMPROVEMENT IN CARBURETERS.

Specification forming part of Letters Patent No. 140,998, dated July 22, 1873; application filed January 16, 1873.

To all whom it may concern:

Be it known that I, Frsnnn AMEs FISHER, of Elizabeth, in the county of Union and State of New Jersey, have invented an Improvement in Regulators of Feed-Liquid in Gas-Carbureters; and I hereby declare the following to be a full and sufficient description of the same, reference being had to the accompanying drawings and references making part of the same.

In the drawings, let Figure 1 represent a vertical section of the regulator; Fig. 2 represents avertical section of gas-carburetor with the improved regulator applied thereto.

The invention consists in a new device for controlling the feed-liquid of a gas-carbureter by means of a verticalconic valve through which said liquid passes to the carburetingchamber.

Directing the eye to the figures, we see the form of a complex cylinder, the upper part being a portion of a smaller cylinder, and the lower part a portion of a larger cylinder. In the upper portion is contained a conic valve, 0, and in the lower a float, D, which, in its normal position, rests on the bottom of the carburetingchamber. The float and the conic valve are connected together by a swiveled valve-rod or piston having a swivel in its middle part, just above which is located cup K, formed by a flanged extension of the under and inner side of the so-called dome E, which extension inclines obliquely downward and inward; then horizontally inward; then vertically upwardformin g, first, the outside of cup K; secondly, the bottom; and thirdly,.the inner side of said cup. The inner side of said cup is extended upward to a little above the holes a which discharge into groove d, and thence over the top of dome E into and through the carbureting-chamber. To form the counterpart of cup K, the inverted cup 0 is provided, which is attached centrally to the said valve-rod, and plays up and down with it, opening and closing valve 0, and at the same time shutting off the chamber of the float from that of the carburetor, thus forming a waterjoint. In the middle part of the valve-rod is the swivel-jointG, which allows a limited side movement, so as to give a free up-and-down movement of the float and conic valve.

To adapt this regulator for working a car a capacious chamber hung around with Wicking or other absorbent material, and constituting the carbureting-chamber-that is to say, an opening ismade into said chamber large enough to receive said regulator, and the opening thoroughly closed up. A series of perforated tubes, m, radiate from the body of the complex cylinder into the carburetingchamber to equally distribute the gas received by induction-pipe Z, and discharge the same by eduction-pipe X.

The distributing-liquid is operated as follows: As stated above, the liquid, after leaving cap B and passing through conic valve 0, (see Fig. 2,) passes downward to cup K, filling it and emptying its contents through holes a into the circular groove (1, whence it flows over the dome E, and is spread through the wickin g of the carbureting-chamber, through which the gas is constantly passing to be carbureted, and from which it is finally discharged from the machine. Now, if an excess of feed-liquid accumulates in the lower part of the carbureter, the float rises up and pushes up conic valve 0 into its recess, and stops the flow through the valve until the wicking absorbs up the excess and the float sinks, opening conic valve 0, and the liquid flows as before. Thus the apparatus described constitutes the combination of an automatic feed liquid regulator with a gas-carburetor.

This invention does not consist in the mere controlliu g of the feed-liquid through the conic valve by means of the float, irrespective of the manner in which it is distributed to or through the carbureter. If the feed-liquid has been allowed to fall into the float-chamber without being distributed through the upper part of the distributingcarbureter, (as is done in the carburetor referred to by the Office,) the car bureting-chamber would have been without effect and valueless but when the double cup K is interposed, acting as a water-joint to sep arate the carbureting from the valve float chamber, new effects are produced. The feedliquid of the conic valve, falling into cup K, is distributed through the holes a upon the dome E, and so through the carburetingchamber hung with wicking.

Having stated the nature of my invention, and the mode of using the same, what I claim as new, and desire to secure by Letters Patent, is-

The combination of the cup K for receiving the feed-liquid and discharging it through the Wicking 0r carbureting-chamber with the inverted cup 0 for forming, with said cup K, a Water-joint that shuts off the liquid from the float-chamber, substantially as and for the purpose specified.
